Izinzuzo zethu    

Izinqubo zokukhiqiza zaseShayina ziye zabhekana neminyaka yokuphindaphinda, okuholele kubuchwepheshe obuvuthiwe nobuthembekile. Izinkampani eziningi zamazwe ngamazwe zikhetha ukukhiqiza ukukhiqiza eChina. Njengomkhiqizi wezingxenye ze-elekthronikhi e-China, imikhiqizo yethu ingangena esikhundleni ngokuphelele semikhiqizo emikhulu yamazwe ngamazwe kuma-99% wezinhlelo zokusebenza ngaphandle kwesidingo sokuqinisekisa ukuhlolwa. Imikhiqizo yethu iqhosha ngokungaguquguquki okuphezulu ngekhwalithi, amanani entengo aphusile, i-inventory eyanele, ukunikezwa okuvumelana nezimo, izikhathi zokuhola ezimfishane, kanye nesevisi yobungcweti ngemva kokuthengisa.    

Incazelo
I-DS1302 iyichip yewashi lesikhathi sangempela (i-RTC) ekhokhisekayo enesivinini esincane esifaka iwashi/ikhalenda lesikhathi sangempela kanye namabhayithi angu-31 we-RAM engaguquki engaguquki. Ixhumana ne-microprocessor nge-interface elula ye-serial. Iwashi/ikhalenda lesikhathi sangempela libala imizuzwana, imizuzu, amahora, izinsuku, amasonto, izinyanga, neminyaka, lizilungisa ngokuzenzakalelayo izinsuku zokuphela kwenyanga izinyanga ezingaphansi kwezinsuku ezingama-31 futhi ihlanganise nokulungiswa konyaka we-leap. Iwashi lisebenza ngefomethi yamahora angu-24 noma ngefomethi yamahora angu-12 enenkomba ye-AM/PM. Amabhayithi angu-31 e-RAM angagcina idatha ebalulekile okwesikhashana. Ukuxhumana kwe-Serial okuvumelanayo kwenza kube lula ukuhlanganisa i-DS1302 ne-microprocessor, edinga izintambo ezintathu kuphela: (1) i-RST (setha kabusha), (2) I/O (umugqa wedatha), kanye (3) ne-SCLK (iwashi lomkhiqizo). Idatha ingadluliselwa ngefomethi yebhayithi eyodwa noma ifomethi ye-multi-byte kufika kumabhayithi angu-31 ngesikhathi. I-DS1302 isebenza ngokusetshenziswa kwamandla okuphansi kakhulu, igcina idatha nolwazi lwewashi ngamandla angaphansi kuka-1μW.

Izici

● Ibala imizuzwana, imizuzu, amahora, izinsuku, amasonto, izinyanga, kanye neminyaka eyisinxephezelo sonyaka.
● Ifaka amabhayithi angu-31 we-RAM engaguquki engaguquki ukuze kugcinwe idatha enesivinini esikhulu.
● Ibanga elibanzi le-voltage yokusebenza: 2.0V kuya ku-5.5V.
● Ukusetshenziswa kwamandla okuphansi okungaphansi kuka-300nA ku-2.5V.
● Isekela ukudluliswa kwedatha ye-single-byte noma i-multi-byte yewashi noma imisebenzi yedatha ye-RAM yokufunda/ukubhala.
● Isixhumi esibonakalayo esilula sezintambo ezi-3 sokuxhumana nama-microcontroller.
● I-TTL iyahambisana (VCC=5V). ? Izinga lokushisa lezimboni ozikhethela lona lisukela ku--40°C kuya ku-+85°C.
